The default behaviour is to read all available light ids from the bridge.
By supplying an array of integers, this default can be overridden in the case that the order of lights on the bridge does not match the ordering of the lights in the configuration file.

The light ids can be obtained from your bridge under the following url:
`http://ip-of-your-bridge/api/username/lights/`

Switch lights off on black color
Not all colors can be displayed by the Philips Hue devices and black will result in a bluish, dark color. Therefore, you can let Hyperion switch off your lights when the light should be black:

Code:

"switchOffOnBlack" : true

It should be noted, that switching on / off takes more time than a color change due to a fading animation of the device.

Rate limitation
The performance of the Philips Hue system is limited. The bridge can handle up to 10-30 requests / second.
Due to this limitation, the framegrabber frequency should be set to _10 / number-of-lights Hz_. This is an example for two lights
